Overview of Parts Unlimited OEM-Type Piston Assembly - 66mm Bore - 8041
  • Dennis Kirk has high-quality, OEM-type piston assemblies to fit most popular snowmobiles
  • These pistons more closely match the original equipment in ring design, construction and weight than our other aftermarket pistons
  • Its not necessary to replace both pistons in a twin-cylinder engine if you need only one
  • All piston assemblies include rings(s), wrist pin and circlips
  • Right Hand Side
  • Bore Size: Standard


  • NOTE: Dennis Kirk recommends the following preliminary work to be performed by a qualified mechanic prior to installing new pistons. If the old piston has failed, determine the cause and remedy the problem before replacing. Air leaks and/or a lean fuel mixture are the two biggest causes of burned pistons. In cases where any part of the old piston is broken or burned through, the crankcase should be disassembled and throughly flushed of any debris.

    Our pistons, rings and kits are sold by application and bore size. Please note that STANDARD and OVERSIZES are not indicated. To get the correct part, you must know the standard bore size to make sure you are ordering either the standard or correct amount of oversize that you need. If you have any questions, please call Technical Service.

What is the difference between the 8040 piston and the 8041? Both are listed as 66mm.
TWoylf on Sep 7, 2016
BEST ANSWER: I believe one is for the PTO side and the other for the Mag. side. Transfer ports on this engine are offset requiring different pistons...
